According to Chapter 52, how did the 'Sai Satcharitra' come to be written and what is its purpose?

Chapter 52 of the Sai Satcharitra explains that the book, also referred to as "Sai Leela," was written to serve as a retrospective review and remembrance of the experiences Sai Baba gave to His devotees while He was in His body. The chapter highlights that Sai Himself chose Hemadpant to author this true life story, holding his hand through the process despite Hemadpant's own feeling of being devoid of specialized knowledge. The inspiration for the book came after Sai's Mahasamadhi, building upon stories Sai Himself had narrated. Its ultimate purpose is described as supremely holy, providing enlightenment for this world and the next, and serving as a written record of Sai's fame for the salvation of His devotees.
